We investigated infections with Gasterophilus spp. in three equids within the Kalamaili Nature Reserve (northern China). We conducted necropsies on 6 Przewalski’s horses (Equus ferus przewalskii) and 6 Mongolian wild asses (Equus hemionus) and administered ivermectin to 10 overwintering domestic horses to expel parasites during winter periods. All 22 equids studied (100%) were infested with Gasterophilus spp. and a total of 17,225 larvae were collected. These included six species: G. haemorrhoidalis, G. inermis, G. intestinalis, G. nasalis, G. nigricornis, and G. pecorum. The mean intensity of Gasterophilus spp. larvae was 1904 in Przewalski’s horses, 780 in Mongolian wild asses, and 113 in domestic horses. Gasterophilus pecorum was the most abundant species in all three equids. Przewalski’s horses, a reintroduced species, had a significantly higher intensity of Gasterophilus spp. than the Mongolian wild ass, indicating greater susceptibility to parasites in its ancestral home.
Résumé
Nous avons étudié les infections de Gasterophilus spp. chez trois équidés dans la réserve naturelle de Kalamaili (Chine du Nord). Nous avons effectué des autopsies sur 6 chevaux de Przewalski (Equus ferus przewalskii) et 6 ânes sauvages de Mongolie (Equus hemionus) et administré de l’ivermectine à 10 chevaux domestiques hivernants pour expulser leurs parasites pendant les périodes d’hiver. Tous les 22 équidés étudiés (100 %) étaient infestés par Gasterophilus spp. et un total de 17,225 larves ont été recueillies. Elles comprenaient six espèces : G. haemorrhoidalis, G. inermis, G. intestinalis, G. nasalis, G. nigricornis et G. pecorum. L’intensité moyenne des larves de Gasterophilus spp. était 1904 chez les chevaux de Przewalski, 780 chez les ânes sauvages de Mongolie et 113 chez les chevaux domestiques. Gasterophilus pecorum était l’espèce la plus abondante chez les trois équidés. Les chevaux de Przewalski, une espèce réintroduite, avait une intensité significativement plus élevée de Gasterophilus spp. que les ânes sauvages de Mongolie, ce qui indique une plus grande sensibilité aux parasites dans leur aire ancestrale.
